MUSIC-LEAF TURNER.

Application filed April 25, 1912.

To all whom it may concern:

Be it known that I, NOLAND B. REES, Jr., a citizen of the United States,residing at Lincoln, in the county of Lincoln, State of Kansas, haveinvented certain new and useful Improvements in Music-Leaf Turners; andI do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to improvements in music leaf turners.

The principal object of the invention s to provide a music leaf turnerwhich is adapted to be placed in position on a plano, organ, or otherinstrument, and by means of which the different sheets of a plece ofmusic may be rapidly and easily turned.

Another object of the invention 1s to provide a music leaf turner forthe purpose described by means of which either the sheets of music maybe independently turned 1n progression or all of said sheets may beturned simultaneously.

A further object of the invention is to provide a music leaf turnerwhich is capable of being adjusted to accommodate sheet music ofdifferent sizes.

A still further object of the invention is to provide a music leafturner of the character described which is composed of a minimum numberof parts, is therefore simple in construct-ion, and is cheap tomanufacture.

lVith these and other objects in view, the invention consists in theconstruction and novel combination of parts hereinafter fully described,illustrated in the accompanying drawings and pointed out in the claimshereto appended; it being understood that various changes in the form,proportion, size and minor details of construction within the scope ofthe claims may be resorted to without departing from the spirit orsacrificing any of the advantages of the invention.

In the drawings: Figure 1 is a front elevation of a music leaf turnerconstructed in accordance with my invention, Fig. 2 is a similar viewshowing the rear face thereof, the parts being shown in their otherpositions, Fig. 3 is an enlarged front elevation showing the meansemployed for pivotally mounting the sheet engaging arms, Fig. 4 is anenlarged detail horizontal sectional Specification of Letters Patent.

view taken on the line t- 1 of Fig. 3, Fig.

5 is a vertical sectional view taken on the line 5-5 of Fig. 3, and Fig.6 is an enlarged detail sectional view showing the means for adjustablyconnecting the supporting bar to the back board.

Like reference numerals designate corresponding parts in all the figuresof the drawings.

Referring to the drawings, 5 designates a back board of any suitableconstruction. This board is centrally formed at its top portion with arectangular opening 6 and in its lower portion on opposite sides of thecenter with sets of vertical slots 7 and 7 respectively. Secured to theboard 5 on opposite sides of the opening 6 are metallic strips 8 andextending forwardly from the inner longitudinal edges are centrallydisposed perforated ears 99, in which is ournaled a pivot pin 10.Secured upon the front face of the board on opposite sides of theopening 6 are cleats 11-11 adapted for a purpose hereinafter more fullyexplained.

My invention further comprises a plurality of laterally swinging arms12, there being preferably five of these arms, although a smaller orgreater number may be employed if so desired. These arms are arrangedone above the other and the lengths of these arms increase inprogression from the bottom arm upwardly. These arms are fulcrumedadjacent their inner ends upon the pivot pin 10, and are disposed inspaced relation to each other by means of washers 13 or other suitablespacing means. Slidably mounted upon each arm is a leaf-engaging clip15. By this arrangement music of various sizes may be readilyaccommodated.

Secured upon the rear face of the back board 5 and on either side of theopening 6 are plates 16 and 17 respectively. A plurality of spaced bellcrank levers 18 are each fulcrumed, as at 19, upon the plate 16, therebeing in this instance five of these levers. In order to swing the arms12 so as to turn the music, the inner end of each arm 12 is connected toone end of a flexible wire 20 or the like, and this wire has its otherend connected to one arm of a respective lever 18. The other arms of thelevers 18 are each connected to one end of a pull rod 21, the lower endof each pull rod being bent at right angles to form a finger-piece 22which projects through one of the slots 7 on the it is desired to turnall of the music at once the finger-piece 22 on the extreme right willbe depressed, and as a result, the arm 12 which engages the last sheetof music will be actuated. The swinging movement of this arm will carrywith it the last sheet of music and as a result will cause the othersheets to travel therewith.

In order to return any of the sheets of music to their normal position,there is fulcrumed upon the plate 17 a plurality of bell crank levers23, and connecting one arm of each lever with one end of a respectivearm 12, is a flexible wire 2 1 or the like. Pull rods 25 are eachconnected at one end with one arm of a respective lever 23 and the lowerends of these rods are bent forwardly at right angles, and terminate infingerpieces 26 which project through the slots 7 on the left hand sideof the board. It will thus be observed that when the arms 12 are intheir normal positions, the finger-pieces 22 will be up and the fingerpieces 26 will be down so that upon the depression of the firstmentioned finger pieces in progression, the sheets of music may beturned in order. As the arms 12 thus swing, the pull rods 25 andconsequently the finger pieces 26 thereof will be elevated, thus placingthem in their proper operative positions ready to return the music.

In order to hold the pull rods 21 and 25 against the board 5 and yetpermit of free movement there is provided a flat strip of metal 27 whichis transversely secured to the back of the board by any suitable means,and has its free ends disposed over the pull rods, the free ends servingto hold the pull rods against the board and consequently preventing thefinger pieces from working rearwardly through their respective slots.

In order to accommodate the board 5 to music of different sizes, thereis adjustably mounted upon the front face of the board a transverselydisposed supporting bar 28. This bar carries at its ends rearwardlyprojecting pins 29-29, the heads engaging within slots 3O 3Orespectively formed in plates 31-31 which are secured to the board 5 andextend longitudinally therealong. The heads frictionally engage saidplate, and thereby retain the bar 28 in any adjusted position. It willthus be observed that the bar can be readily raised and lowered toaccommodate music of different sizes.

Secured to the upper portion of the left hand side of the board 5 is aspring clip 32 for holding the first sheet of music against movement.

lVhat is claimed is:

1. In a music leaf turner, the combination with a back-board having anopening centrally formed in its upper portion and a second openingformed in its lower portion on one side of the center, of a verticalpivot pin supported by the board and disposed across said opening, ahorizontally swinging lever fulcrumed adjacent one end on said pin andforming consequent long and short arms, a leaf-engaging clip carried bythe long arm of said lever, means connected to the short arm of thelever for swinging the same, a bell crank lever pivoted at its angle tothe rear face of the board, a flexible connection between the short armof the lever and one arm of the bell crank lever, and a pull rodconnected at its upper end to the other arm of the bell crank lever andhaving its lower end bent at right angles and projecting through thesecond mentioned opening and constituting a finger-piece.
